Klaus...Groups and Elements...

BTW: If it were not for the painted markings on the teleconverters, you could not visually see any difference between the Vivitar Series 1 1.4X, Tanron-F 1.4X Pz_AF, Kenko 1.5X Pz_AF, and Promaster Spectrum 7 1.7X Pz_AF. The only difference that I can see is that the Promaster 1.7X rear element is 25mm and all of the others are 27mm.

In addition:

(1) - The Tamron-F 1.4X Pz_AF has 4 elements in 4 groups.

(2) - The Kenko 1.5X Pz_AF has 5 elements (groups unknown to me).

(3) - The Vivitar Series 1 1.4X has 4 elements in 4 groups.

(4) - The Promaster Spectrum 7 1.7X Pz_AF has 4 elements in 4 groups

Cheers.
